Summary

Senior🎓
Top SchoolStephen Coogan is a staff software engineer based in Dublin with 13 years of hands-on front-end experience, currently shaping frontend architecture and delivery at Personio. He’s passionate about web standards, free/open tech, and building polished, performant interfaces—often advocating testing-first practices and component-driven design to enable rapid, low-incident releases. Previously he led front-end architecture at CarTrawler, where he drove a monorepo, comprehensive testing (unit, E2E, visual), Lighthouse CI, and a framework-agnostic design system that bridged Engineering and Design. Known wryly on GitHub as a “Professional Mistake Maker,” he combines pragmatic experimentation with disciplined engineering to ship reliable UIs at scale.
